CP Piston & Ring Set for Audi/VW 1.8L 20V - Bore (83mm) - Compression Ratio (9.5:1) - Set of 4

Forged from high-strength 2618-T61 aluminum, these CP Pistons are built to handle the demands of performance Audi and VW 1.8L 20V engines. The 83mm bore size is a direct replacement for stock, while the 9.5:1 compression ratio offers a solid balance for both naturally aspirated and boosted applications, providing improved power without excessive cylinder pressures. This set includes four pistons and their corresponding rings, ready for your engine build.

CP Pistons are known for their robust construction and precision manufacturing. Each piston in this set is CNC-machined for accuracy, ensuring consistent performance and reliability. The 2618-T61 aluminum alloy is chosen for its excellent strength-to-weight ratio, which is crucial for high-performance engines that experience significant thermal and mechanical stress. This material choice helps prevent distortion and maintains proper piston-to-wall clearance under extreme conditions.

This piston and ring set is designed as a direct fit for the Audi/VW 1.8L 20V engine. While these pistons are well-suited for performance builds, it's important to note they are not CARB approved and cannot be shipped to California. For optimal results and longevity, ensure proper installation procedures are followed, including correct ring gap settings and cylinder wall preparation, referring to the manufacturer's installation guide for specific details.
